How to handle when your hamster isn't moving

What should you do if you find your hamster lying still and motionless? What could be the cause? Hamsters occasionally enter a hibernation-like state, where their heart rate and breathing slow down significantly, and they fall into a deep sleep. It can be hard to determine if your hamster is hibernating or has passed away. If you find your hamster in this state, here's what you should do.

Consider whether the hamster has become suddenly immobile. Has your hamster appeared sick recently? Clues to this include the hamster refusing to eat or drink, drinking more water than usual, you needing to clean its bedding more frequently, a foul odor coming from the hamster, significant weight loss, or noticeable behavioral changes, such as no longer playing on its wheel. All of these signs point to the hamster being ill and possibly deceased.

• On the other hand, if the hamster seemed completely healthy beforehand and became immobile suddenly, it might be in hibernation, though death cannot be ruled out.

How old is your hamster? The average lifespan of a hamster is between 18 to 24 months, with some living up to 36 months. If your hamster is beyond this age, it is considered quite old, and the likelihood of it passing away is high.

Consider the environmental temperature. Hibernation is influenced by temperature. If the temperature inside your hamster's cage exceeds 20°C, it is unlikely that the hamster is hibernating. On hot days, check whether the cage is placed near an air conditioner. The cold air from the AC could induce hibernation, so temperature factors should not be ignored, even on hot days.

Assess your hamster's access to food and light. Hibernation usually occurs when hamsters struggle to find enough resources to survive. These conditions are typically associated with harsh winters, where temperatures drop, daylight hours shorten, and food becomes scarce.

• Think about whether your hamster is getting 8-12 hours of sunlight a day and has enough food. A lack of food combined with low temperatures and short daylight hours can trigger hibernation.

Observe whether your hamster is breathing. If you suspect that your hamster is hibernating, watch it closely for a few minutes. Look for signs of breathing. Note that the hamster's entire body is slowing down, so its breathing rate may be as slow as every 2 minutes.

• Observe the hamster for more than 2 minutes, as a brief lapse in attention might cause you to miss a breath. If you only watch for exactly 2 minutes, you may mistakenly think that the hamster has passed away.

Try checking the heart rate. If you don't see your hamster breathing, try feeling for its heartbeat. The hamster's heart rate may slow down significantly, down to 4 beats per minute or even 1 beat every 15 seconds.

• The hamster's heartbeat might be difficult to find due to its small size. To do this, place your thumb and index finger on one side of the hamster, just behind its front legs. Gently press, as if trying to stop the hamster from running without causing harm. Be patient and feel for the heartbeat beneath your fingers.

Do not rely on body temperature when distinguishing between hibernation and death. Don't be alarmed if your hamster feels cold to the touch. A cold hamster doesn't necessarily mean it's dead. Hibernation is triggered by cold temperatures, causing the body temperature to drop to match the environment.

Check the stiffness of the hamster's body. Rigor mortis is a key indicator that a hamster has passed away. If the hamster feels stiff like wood, it is in the rigor mortis stage, meaning it has died.

Move your hamster to a warm room. The room temperature should be around 20°C. Wait for 2-3 days. If your hamster is simply hibernating, it will wake up within this time frame.

• If the hamster doesn't wake up, further signs will become evident that it has passed away, such as stiffness and a foul odor. A hibernating hamster will not emit any odor.
• Experts recommend this method to wake the hamster, as it mimics the natural awakening process and places less strain on the hamster's blood glucose reserves compared to a 'quick-start' method.
• Be sure to provide plenty of food and water when the hamster wakes up.

Quickly warm up the hamster to a moderate level. Instead of gradually warming up your hamster in a warm room, you can speed up the process. Place the hamster's cage in a warm area, such as on a dish rack. Depending on the temperature, the hamster may wake up within 2-3 hours.

• Remember to place the hamster in a secure box, as leaving it in a cardboard box may lead to it chewing through the box and escaping once it wakes up!
• Another method is to place the hamster's cage on top of a hot water bottle to allow heat to rise from the bottom of the cage.
• Ensure the hamster has food and water, as it will use a lot of energy to wake up, and it needs to be replenished quickly. Without proper nutrition, your hamster could suffer from liver damage.

Keep in mind that hibernation is a natural process. If your hamster is hibernating, you should understand that this is a natural process, and it will recover. Unless you are extremely worried, if the hamster resumes its usual activities like eating, grooming, and playing with the wheel, there's no need to take it to the vet.

Don't forget that hamsters have a short lifespan. If you've tried everything to wake up your hamster and it doesn't respond, it may have passed away. The life of a hamster is short, and unfortunately, it may have reached the end of its life. Eliminate all other possibilities first, but eventually, you might need to accept that your hamster has died.

Prevent future hibernation in hamsters. If you don't want to worry about your hamster hibernating again, you need to make sure it's always in an environment with temperatures above 20°C, receives more than 12 hours of light each day, and has ample food and water. This way, the hamster's body will never signal that it needs to conserve energy by entering hibernation.

• Breeders of hamsters prioritize preventing their pets from entering a hibernation state. Their advice is to maintain a room temperature of 20-21°C year-round, provide 12-14 hours of light each day (artificial lighting can be used), and offer plenty of food. Under these conditions, hamsters will not feel the need to hibernate and will remain active.
